I havent touched my n gauge train in about 15 years so it is pretty well weathered, having been hanging in my garage all this time . I have also realized that I am way behind the times electrically now that DCC is available. In reading how you just connect two wires to your track, am I being overly optimistic in thinking that one can install a DCC unit on the existing layout which is completely electically blocked by turning all the blocks on and connecting one wire of the DCC to the main bus for the blocks and the second wire for the DCC to the other track?????. I know I am missing something someplace and it can not be this simple. I dont have any reversing loops or wyes to worry about. I will look forward to your help and suggestions.
